Coloration. Resembles M. obscura, but differs in the following 

 respects : — the breast and sides of the body in both sexes are slaty 

 grey, not chestnut-brown ; the upper plumage in both sexes is 

 russet-brown, not olive-brown ; the crown in the adult male is never 

 darker than the other upper parts ; the sides of the head and the 

 sides of the chin and throat are russet-brown, not slaty brown ; 

 and in the adult male the throat itself is slaty grey, not slaty brown. 



Iris deep chocolate ; bill black ; legs pale cloudy brown ( Wardlaw 

 Ramsay) ; legs and feet brownish yellow ; bill blackish brown, 

 yellow at gape and on base of lower mandible ; iris brown (Hume). 



Of the same dimensions as M. obscura. 



This Ouzel resembles M. pallida, Gmelin, but may be instantly 

 distinguished from that species by the presence of a supercilium, 

 which is altogether absent in M. pallida. The latter inhabits 

 Eastern Asia and may occasionally visit Burma. 



Distribution. Shillong and Cherra Poonjee ; Japvo peak in the 

 Naga hills at 10,000 feet; Manipur; Karennee at 5000 feet; 

 Muleyit mountain in Tenasserim. 



All the specimens of this species that I have examined from the 

 above localities were procured in the winter months, but this Ouzel 

 is not unlikely to prove a resident species in those parts. 



Genus GE0CICHLA, Kuhl (teste Gould), 1836. 



In the Thrushes of this genus the sexes are different and the 

 under wing-coverts and axillaries are each of two colours, the 

 position of the two colours on the under wing-coverts being 

 transposed on the axillaries. 



From Menda this genus differs in having a somewhat blunter 

 wiug and shorter tail. The underside of the wing presents a 

 pattern formed by the white bases of many of the quills.
